. Find the mean of the number of cheating students from the Technical-Vocational and Livelihood track during midterms and finals. 8. Find the mean of the number of cheating students from the Academic track during midterms and finals. 9. Find the standard deviation of all the number of cheating students during midterms.
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.

A group of researchers wants to determine if tardiness encourages students to cheat during
quarterly exams. Below is a frequency table of the number of students who cheated during the midterm
and final exam from each strand using observational notes.
